A linear-selective Negishi coupling reaction was developed and the synthesis of the target compounds was achieved by a reaction of (allyl)zinc reagents [i.e., (prenyl)zinc bromide, (farnesyl)zinc, etc.] with aryl halides, heteroaryl halides, vinyl halides. The reaction features mild reaction conditions and a broad reactant scope with respect to aryl halides and vinyl halides and (allyl)zinc coupling components. Under optimized reaction conditions [2′-(amino-κN)[1,1′-biphenyl]-2-yl-κC][2′-(dicyclohexylphosphino-κP)-N2,N2,N6,N6-tetramethyl[1,1′-biphenyl]-2,6-diamine](methanesulfonate-κO)palladium was used as a catalyst. This synthetic approach was applied to the preparation of 6-methyl-3-(3-methyl-2-buten-1-yl)-9H-carbazol-2-ol (siamenol).
